Following your pond threads with interest, and I second Josh's thoughts about LMB--early on in the life of your pond, you may want to run a little heavy in the LMB department, and your idea of adding a few larger LMB this year, perhaps later in the fall, sounds like a good idea. Down the road, when the BH,GSF,crappie are under control, you can always cull if becoming bass heavy.
WRT carp, if you continually work on them, in a pond your size you've got a good shot of controlling long term with persistant pressure. One thing you could try--each time you go to the pond, when you first arrive, try chumming an area with canned corn. After a few visits, chum, and then throw out a couple kernals on a hook, with no wt...over time, you can nuke a lot of carp this way. May have to vary the baits over time, but if you remove every carp you catch, and don't miss too many [let them swallow the hook!], you should be able to get ahead, especially when assisted by a hungry LMB population.
Put a bounty on each carp, and let your kids work on them.
